  • The entry point to Instant, representing a client that can connect to PSPDFKit Server.

    The Instant client manages the descriptors of the documents that you have access to. It provides the container for your downloaded documents, and controls the communication channel to the server. By providing a delegate, you are informed of relevant events regarding the synced documents and can manage tasks like authentication in a centralized manner.
